This case demonstrates the feasibility of performing a left middle lobectomy in a patient with a rare combination of displaced anomalous bronchus and persistent left superior vena cava.
[Abstract] We report a case of an 82-year-old man with displaced anomalous bronchus and persistent left superior vena cava who underwent video-assisted thoracic surgery for lung cancer treatment. Chest computed tomography showed a 3.4×2.5 cm solid tumor in the S4 segment of the left lung. Bronchoscopy showed that B1+2+B3 and B4+5 branched from the left main bronchus separately, and primary lung adenocarcinoma was diagnosed using a transbronchial lung biopsy obtained from B4. Contrast-enhanced chest computed tomography showed that the left main pulmonary artery passed between B 1+2 + B3 and B 4+5 and the left lung had three lobes like the right lung. Furthermore, a persistent left superior vena cava was observed. The patient underwent left middle lobectomy and no recurrence was noted for 9 years. To our knowledge, this is the first report of middle lobectomy in the left lung for treating lung cancer.

Takemoto et al. (2022) conducted a case report in Lung adenocarcinoma with displaced bronchus and persistent left superior vena cava (n=1). Video-assisted left middle lobectomy and lymph node dissection was evaluated on Cancer recurrence. Video-assisted left middle lobectomy successfully treated an 82-year-old man with lung cancer and rare anatomical anomalies, with no recurrence observed over a 9-year follow-up period.
